An undershot waterwheel consists of a series of flat vanes, mounted radially on a wheel of large diameter, which are struck normally by a jet of water 0.3 m in diameter. If the velocity

of the water leaving the nozzle is 7.5 m/s and the velocity of the vanes is 4.8 m/s, determine:

i. The force exerted by the jet on the vanes;

ii. The work done per second;

iii. The hydraulic efficiency.​

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
